Abstract: In the context of building digital China, it is particularly important to enhance digital governance capabilities to promote digital synergy innovation. Based on the Chinese regional governance framework, this study takes 278 cities in China as cases to explore the linkage effect and path selection of digital governance elements on the digital synergy innovation at different time periods. The results show that: (1) Digital synergy innovation can be divided into an embryonic period and a rapid development period, with a hierarchical effect in space. The eastern region has obvious advantages, while the central and western regions are accelerating their rise. (2) There are six high digital synergy innovation paths in the embryonic stage, which can be classified as digital government-environmental type and digital government-industrial type. There are five paths in the rapid development period, which can be classified as digital government-environmental type, digital industry-social type, and multi-dimensional synergy type. (3) Considering the evolution trend, in terms of single factors, digital infrastructure and innovation environment have always played an important role, and digital industry is prominent during the rapid development period; In terms of the relationship model, the digital government-environment type is relatively stable and gradually evolving towards a multi-dimensional synergy type. (4) Cross case comparisons find that there are differences in the improvement paths of digital synergy innovation in different regions. This study helps to grasp the digital synergy innovation current development, and provides important insights for exploring development paths at different time periods, improves the digital governance system, and accelerates the digital China construction.

摘要： 在数字中国背景下，如何提升数字治理能力以推动数字协同创新显得尤为重要。基于中国式区域治理框架，以278个地级市为案例，探究不同时段数字治理要素对数字协同创新提升的联动效应及路径选择。研究发现：（1）数字协同创新时间上分为萌芽期和快速发展期，空间上呈层级效应，东部优势明显，中西部加快崛起。（2）萌芽期存在6条高数字协同创新路径，可归为数字政府-环境型和数字政府-产业型。快速发展期存在5条路径，可归为数字政府-环境型、数字产业-社会型和全维度协同型。（3）考虑数字治理演化趋势，单要素而言，数字基础设施和创新环境始终发挥重要作用，数字产业发展于快速发展期作用凸显；关系模式而言，数字政府-环境型模式相对稳定，且逐渐向全维度协同型演进。（4）跨案例比较发现，不同区域数字协同创新提升路径存在差异。本研究有助于把握数字协同创新发展状况，为探索不同时段发展路径、完善数字治理体系、加速数字中国建设提供重要启示。
